Last post by LubOlimex - September 09, 2025, 10:57:07 AMAs you noticed by default SAM9-L9260 comes prepared with Linux. This Linux image and sources can be found in this this ISO - mount it and explore the contents inside:
https://ftp.olimex.com/Obsolete_images/SAM9-L9260/SAM9-L9260_Rev.D.iso
Notice that SAM9-L9260 is not a personal computer, it will not boot Ubuntu 22.04 from a flash drive.

Last post by LubOlimex - September 09, 2025, 08:02:33 AMYeah you can also use jumper wires at the UEXT to save from soldering. Just change the definitions, look at the schematic for the GPIOs of the ESP32 at the UEXT.
This is where I saw about 1106, one of the pictures on the product page:

New Product Ideas / SAM9-L9260 board / Boot to an ...
Last post by TomH - September 08, 2025, 08:37:16 PMHello,
I recenty got an Olimex SAM9_L9260 board. After connecting to a 5V/3A power supply, connecting to a null modem, Hyperterminal, I got the board to boot and was able to login.
Now my questions are:
1. The box the board came in is empty. No quick starting quide. How do I format / boot to an OS on my SD card? I tried to format a 128 MB SD card using Rufus and put Ubuntu 22.04 on it. No go.
2. Is / Are there any jumper(s) I can set so it will boot to SD/MMC card. I see this in the SAM9_L9260 file:
Is the SD/MMC card supported?
A: The SD/MMC card is fully supported, including detection of card insertion/removal and
write lock
3. I also saw this in the PDF file. Where is the NANDF_E and DF_E jumpers are located?
A: Make sure that NANDF_E jumper is not connected and DF_E jumer is connected. If the
dataflash has been correctly programmed, the board should start up
4. I got this from https://www.olimex.com/wiki/SAM9-L9260
git clone -b olimex https://github.com/OLIMEX/at91bootstrap.git
and when I tried to build it using:
make sam9_l9260_uboot_defconfig
this does not work.
What's the latest instruction?

ESP32 / Re: ESP32-POE-ISO and OLED Dis...
Last post by franck67 - September 08, 2025, 05:29:22 PMHi and thanks for your answer.
I didn't see where you saw the 1106 library, but in the the comments i found someone talking about the U8G2 library, so i tried it.
Apparently the pin im supposed to use are also part of the UEXT, so they are easily wirable.
I tried in that way, and it worked like a charm.
I'll keep digging in my corner, but i wont hesitate to come back here if i face some new obstacles
thanks for your help

UEXT / Re: MOD-BME280 SPI
Last post by LubOlimex - September 08, 2025, 02:43:31 PMOnly 3-wire SPI is possible since SDO is either connected to VDDIO or to GND. Using CSB, SDI, SDC 3-wire SPI is possible, refer to the schematic:
https://github.com/OLIMEX/MOD-BME280/blob/master/HARDWARE/MOD-BME280-Rev.B/MOD-BME280_RevB.pdf
And also the datasheet of BME280, page 38, table 35:

Last post by Davide - September 08, 2025, 11:00:44 AMIn the end I moved to A13-OLinuXino-bullseye-minimal-20250305-103314 image and was able to achieve what I needed.
Many thanks for your help. As soon as possible, I will try your solution and update the topic

ESP32 / Re: ESP32-POE-ISO and OLED Dis...
Last post by LubOlimex - September 08, 2025, 10:39:55 AMLooks good so far. Just you tried a library that is made for another controller? From the Amazon page it seems like the display uses SSD1106 (not SSD1306). Maybe try another library or another demo for SSD1106. Also it is possible that the manufacturer used another controller.
Pins 32 and 33 are fine, just make sure that in your code they are defined for I2C operation.
This is usually done with:
Wire.begin (32, 33);
Best regards,
Lub/OLIMEX

ESP32 / ESP32-POE-ISO and OLED Display
Last post by franck67 - September 07, 2025, 08:14:24 PMHello everyone,
i am relatively new to all of this, so some of my questions might seem odd, i apologize in advance
I started to get interested in those boards, because i want to monitor the production of my solar panels in real time without subscribing to any manufacturer's cloud.
I then heard about the openDTU project, which allows to monitor my micro-inverter with an ESP32 board, and an antenna.
I chose the ESP32-POE-ISO because i have a POE switch just next the place i want to set it up.
I now want to add the antenna i bought, and also a OLED display. I chose those 2 :
antenna : https://www.amazon.fr/dp/B09G9GJCXW?ref=ppx_yo2ov_dt_b_fed_asin_title
oled : https://www.amazon.fr/dp/B0CWGP53JW?ref=ppx_yo2ov_dt_b_fed_asin_title
i checked this picture for the wiring :
https://www.opendtu.solar/hardware/olimexpoeiso/#schematic
so i soldered port 32/33 to SDA/SCL and port GND/+3.3 to GND/VCC on my display
Before going further, i would like to see if i can display something on the screen in a easy way.
I'm using Arduino IDE, i could install the board, the port, i can connect to my Olimex board.
I could write a small program that blinks leds on my pin 32 and 33, so it looks like everything on the board and my solderings is working, but when i plug the display, i can't get it to display something.
i downloaded the library Adafruit_SSD1306.h, but then i'm stuck.
Is there a possibility that the 32/33 ports arent the good one ? if yes how to change them since my wires are already soldered ?
Can someone give me a little code to test this screen ? like to write "hello world" or something, so i can be sure i didnt burn something in my tests ?
Thanks a lot for your help

RK3188 / Re: [RK3328-SOM-EVB] Using UA...
Last post by LubOlimex - September 05, 2025, 04:46:21 PMThe fact that it works with the old image means it is software issue in the new image.
I tried this one here:
https://forum.armbian.com/topic/16100-rockpi-e-enabling-uart1-and-otg-using-custom-dt-overlays/
After reboot I see serial1 but it won't work probably something from the old image dts should be copied too. Maybe because the pinout is different.
